    LEM HAH1BVS/26 Open-Loop Hall Effect Current Sensor

     

    LEM HAH1BVS/26 Product Overview

    The HAH1BVS/26 is an open-loop Hall effect current transducer from LEM's HAH1BVS series, designed for electronic measurement of DC, AC, and pulsed currents in high-power and low-voltage automotive applications, with galvanic separation between the primary circuit (high power) and the secondary circuit (electronic circuit).

    The HAH1BVS series is specifically optimized for automotive Battery Management Systems (BMS), electric vehicles, and hybrid electric vehicle applications, featuring busbar mounting and offering various current measuring ranges in the same housing for flexible platform-based selection.
